1 month ago you probably need to use the coredump to get a backtrace of what the program was doing when SIGABRT happened.
don't upload the entire coredump here since there might be sensitive data in memory - but you can run gdb on the coredump like this to get a backtrace:
gdb /usr/bin/sshfs /path/to/coredump
then in the gdb prompt, type bt and paste the output here.

Hi team,
I figured out an issue today. Since os migration to almalinux 8.9, the sshfs process killed after few minutes and the mountpoints aren't unavailable. In production, it's very terrible because, many clients are concerned.
In below, you'll see the report from abrt tool:
